Precision Raceworks High Performance Fuel Pump Kit - Stage 4.5 - BMW F-Chassis S55

Product Details

If you are looking to get more power out of your BMW, it's important not to forget your fueling system! Your low and high-pressure fuel pumps can only flow so much fuel, limiting power potential regardless of turbo size or other power adders, especially true when running ethanol blends.

Upgrade your BMW fuel pump with Precision Raceworks' F-Chassis High-Performance Fuel Pump Kit. Precision's low-pressure fuel pumps are designed to flow significantly more fuel than your BMW's stock system, ideal for customers who are upgrading their vehicles or plan to run blended fuel or E85 alone! Best of all, these pumps ship completely assembled and ready to install! New pump, new fuel filter, and new sending unit included! This is a true plug-and-play solution that anyone can install in their home garage and start taking advantage of the benefits right away.

By design, a fuel pump such as this is ideal for daily driving and racing applications of all kinds. This system keeps the primary pump fully submerged in fuel regardless of tank level or the g-force the car is subjected to.

Precision Raceworks' Stage 4.5 bucketed/bucketless hybrid fuel pump includes all necessary wiring and pump activation switch (hobbs switch). This pump utilizes the OEM brushless pump in the bucket and a Walbro 525 (F90000285) fuel pump outside the bucket, capable of supporting up to 900whp on 93 octane gas or 850whp on 100% E85. Even better yet? No wires to cut or splice, nothing to assemble, 100% OEM quality, and drop-in ready!
